NAME
ORDB::CPANMeta - An ORLite-based ORM Database API
SYNOPSIS
TO BE COMPLETED
DESCRIPTION
TO BE COMPLETED
METHODS
dsn
my $string = Foo::Bar->dsn;
The "dsn" accessor returns the dbi connection string used to connect to
the SQLite database as a string.
dbh
my $handle = Foo::Bar->dbh;
To reliably prevent potential SQLite deadlocks resulting from multiple
connections in a single process, each ORLite package will only ever
maintain a single connection to the database.
During a transaction, this will be the same (cached) database handle.
Although in most situations you should not need a direct DBI connection
handle, the "dbh" method provides a method for getting a direct
connection in a way that is compatible with ORLite's connection
management.
Please note that these connections should be short-lived, you should
never hold onto a connection beyond the immediate scope.
The transaction system in ORLite is specifically designed so that code
using the database should never have to know whether or not it is in a
transation.
Because of this, you should never call the ->disconnect method on the
database handles yourself, as the handle may be that of a currently
running transaction.
Further, you should do your own transaction management on a handle
provided by the method.
In cases where there are extreme needs, and you absolutely have to
violate these connection handling rules, you should create your own
completely manual DBI->connect call to the database, using the connect
string provided by the "dsn" method.
The "dbh" method returns a DBI::db object, or throws an exception on
error.
selectall_arrayref
The "selectall_arrayref" method is a direct wrapper around the
equivalent DBI method, but applied to the appropriate locally-provided
connection or transaction.
It takes the same parameters and has the same return values and error
behaviour.
selectall_hashref
The "selectall_hashref" method is a direct wrapper around the equivalent
DBI method, but applied to the appropriate locally-provided connection
or transaction.
It takes the same parameters and has the same return values and error
behaviour.
selectcol_arrayref
The "selectcol_arrayref" method is a direct wrapper around the
equivalent DBI method, but applied to the appropriate locally-provided
connection or transaction.
It takes the same parameters and has the same return values and error
behaviour.
selectrow_array
The "selectrow_array" method is a direct wrapper around the equivalent
DBI method, but applied to the appropriate locally-provided connection
or transaction.
It takes the same parameters and has the same return values and error
behaviour.
selectrow_arrayref
The "selectrow_arrayref" method is a direct wrapper around the
equivalent DBI method, but applied to the appropriate locally-provided
connection or transaction.
It takes the same parameters and has the same return values and error
behaviour.
selectrow_hashref
The "selectrow_hashref" method is a direct wrapper around the equivalent
DBI method, but applied to the appropriate locally-provided connection
or transaction.
It takes the same parameters and has the same return values and error
behaviour.
prepare
The "prepare" method is a direct wrapper around the equivalent DBI
method, but applied to the appropriate locally-provided connection or
transaction
It takes the same parameters and has the same return values and error
behaviour.
In general though, you should try to avoid the use of your own prepared
statements if possible, although this is only a recommendation and by no
means prohibited.
pragma
# Get the user_version for the schema
my $version = Foo::Bar->pragma('user_version');
The "pragma" method provides a convenient method for fetching a pragma
for a datase. See the SQLite documentation for more details.
SUPPORT
